·picture quality?
I hear people(who just have the standard def Dish Network recievers and don't even have a 6000) say stuff like Dish has PERFECT picture quality, or Dish has a DVD quality picture and stuff. I feel like I'm in an episode of The Twilight Zone or something. Many people on dbsforums, dbstalk, and the newsgroups have said that Dish's standared def channels have "a perfect picture" or that they have a "dvd quality picture".
I like how most of the people at AVSforums call a spade a spade and say flat out how bad Dish's standard def channels are. Some of them say that they don't even watch Dish's Standard def channel ever anymore because of the overcompression.
Many people have done calculations with their PVRs and found that that some times the standard def Dish channels go as low as 2.5 Mbps or even lower.
I'll give you comparisons of how bad that really is.
Keep in mind that it's on a logrythmic scale and NOT on a linear scale so that 5.0 Mbps may be like 3 times or even 10 times better picture quality than 2.5 Mbps and not just double the way it would be on a linear scale.
From what I've read UNcompressed 720x480 digital video WITHOUT even sound takes up 250Mbps of bandwidth.
So even if you were to use a lossless compression type, it would still require like around 125Mbps of bandwidth.
A superbit DVD has about 6.0 to about 7.3 Mbps of bandwidth.
Even the regular dvds with the whole bunch of bunch of trailers, bonus footage, comentary, and other stuff probably runs at 3.75 to 5.0 Mbps.
So unless somebody can prove that a certain standard def Dish channel they were watching was getting at least 3.75Mbps or that Dish is somehow using a VASTLY VASTLY superior compression method than dvds, then nobody should ever say that Dish's standard def channels have a dvd quality picture.
The only way I'd give a dish standard def channel a perfect score for picture quality(considering it's technical limitations) is if it was getting an entire transponder(which is like 27 to 30Mbps), and if Dish had component outputs on even the standard def recievers.
